Answer:
x = 4 + sqrt(5) or x = 4 - sqrt(5)
Step-by-step explanation:
Solve for x:
(x - 4)^2 = 5
Take the square root of both sides:
x - 4 = sqrt(5) or x - 4 = -sqrt(5)
Add 4 to both sides:
x = 4 + sqrt(5) or x - 4 = -sqrt(5)
Add 4 to both sides:
Answer: x = 4 + sqrt(5) or x = 4 - sqrt(5)
Answer:
Approximately 3.3 cm
Step-by-step explanation:
The volume of a cube is given by
V =s^3 where s is the side length
36 = s^3
Take the cube root of each side
36^ 1/3 = s^3^1/3
3.301927249 = s
Approximately 3.3 cm
Interest = P*r*t
The rate is an annual rate, so time must be in years.
3 months = 1/4 year = 0.25 years
Interest = (300)(0.12)(0.25) = 9
